CARDING-MACHI NE.

SPECIFICATION forming part of Letters Patent No. 347,728',dated August1'7, 1886.

Application filed May 3, 1886. Serial No. 200.914. (No model.)

To aZZ whom it may concern:

Be it known that I, HAMILTON L. MoUL- TON, a citizen of the UnitedStates, residingin Philadelphia, Pennsylvania, have invented certainImprovements inGarding-Mach i ues, of which the following is aspecification. 7 My invention relates to that class of carding-machinesin which more than two doffercylinders and more than two sets ofrub-rolls are used, the intermediate set or sets of rubrolls beingoffset in respect to the upper and lower sets; and the object of myinvention is to provide means for the proper reciprocation of rub-rollsso disposed.

In the accompanying drawings, Fignrel is a diagram showing thearrangement ofdoffingcylinders and rub rolls in connection with which myinvention is used. Fig. 2 is a dia gram showing the arrangement ofdotfing-cylinders and rub-rolls now generally employed. Fig. 3 is a sideview of sufficient of the delivery end of the carding-machine toillustrate one form of mechanism which I employ for reciprocating therub-rolls as arranged in Fig. 1, and Fig. 4 is a view showing a modifiedform of part of the mechanism.

In Figs. 1 and 2, A represents part of the main cylinder of acarding-machine, and B, D, and F respectively the upper, intermediate,and lower doffingcylinders, b, d, and f respectively representing theupper, intermediate, and lower series of rub-rolls.

It has been the general practice hitherto in this class of machines toarrange the three sets of rub-rolls vertically in line with each other,as shown in Fig. 2, the eccentrics for driving the different setsbeingcarried by one vertical shaft, and the eccentric-straps being connecteddirectly to the rub-roll frames; but this plan is objectionable, becauseit necessitates the use of an intermediate dolfing-cylinder considerablyless in diameter than the upper and lower doffing-cylinders.

It is well known that the toothed card-clothing with which thedoffing-cylinders are provided is effective in proportion to the radiusof the are presented by the periphery of the cylinder, the rule beingthat the flatter the are the better will be the duty performed by thecard-teeth, as the points of the latter are not spread apart to the sameextent as when the card-clothing is bent sharply round a cylinder ofsmall diameter; hence there is less tendency for the fiber to becomepacked in around the roots oft-he teeth, and lessliability of the dofferto become clogged. It is much preferable, therefore, to employdoffing-cylinders all of which are of the same or substantially the samediameter, and to offset the intermediate series of rub-rolls to the sameor about the same extent that the center of the intermediaiedoffing-cylinder is offset beyond a line drawn through the centers ofthe upper and lower doffingcylinders, as shown in Fig. 1, for by thismeans the uniform action of each doffer and the production of uniformwork are insured. This construction and arrangement of doffing-cylindersand rub-rolls, however, owing to the lateral offsetting of theintermediate set of rub-rolls, precludes the use of direct connectionsbetween all of the rubroll frames and eccentrics on a single verticaldriving-shaft; hence I employ reciprocating mechanism, the preferableform of which is shown in Fig. 3, in which G represents a frame mountedupon and secured to. the fixed frame, and having bearings for thevertical shaft J, which has the usual eccentrics,b and f ,for reciprocating the frames carrying the upper and lower sets of rub-rolls, band f. The eccentrics d, which effect the reciprocation of the framescarrying the intermediate set of rubrolls, d, are carried by a shortcounter-shaft, K, also adapted to bearings on the frame G, said shaftbeing driven from the shaft J by means of spur-wheels g and h. Theobject of using this counter-shaft is to effect the location of theeccentrics as nearly as possible in a central position laterally inrespect to the frames carrying the intermediate set of rubrolls, so thatthe application of power to reciprocate said frames will not throw themout of balance or cause uneven wear of the eccentrics, frames, orbearings, it being understood that the strap of each of the eccentricsb, d, and f has a rod connected directly to a pin located midway, orthereabout, of the width of the rub-roll frame operated by saideccentrio.

Other means within the scope of my invention for reciprocating theintermediate set of rub-rolls will, however, readily suggest themselvesto those familiar with the class of machinery to which my inventionrelates. For

instance, the shaft J may have intermediate eccentrics, the straps ofwhich are connected to levers pivoted to the f ramc G, and connected tothe frames of the intermediate set of rubrolls, such a modificationbeing shown in Fig. 4.

The shaft J may be driven in any desirable manner, the shaft in thepresent instance having a bevel-wheel, i, which gears with a pinion, m,on a shaft, or, a pulley, p, on which receives a belt, 8, from a pulleyon any available rotating shaft of the machine.

I claim as my invention- 1. The combination of the cylinder of acarding-machine, upper, lower, and intermediate dofiing-cylinders ofsubstantially uniform diameter, upper, lower, and intermediate series ofrub-rolls, the intermediate series being off set in respect to the upperand lower series, frames for said rubrolls, eccentrics for reciprocatingthe rub-roll frames, devices connectiug each eceentric'strap to itsrub-roll frame at a central point on the latter, and mechanismforrotating the eccentrics, all. substantially as specified.

2. The combination of the main cylinder, the upper, lower, andintermediate doffingcylinders of substantially uniform diameter, theupper, lower, and intermediate series of rub-rolls and their frames, ashaft having eccentrics for reciprocating the upper and lower series ofrub-rolls, a counter'shaft having cceentries for reciprocating theintermediate series of rub-rolls, and mechanism whereby the shafts arerotated in unison, all substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HAMILTON L. MOULTON.
